In the previous report, the authors proposed a new procedure of analysing zig-zag test, by which it is possible to identify the parameters of the second-order mathematical model, i. e. ( L/V ) ² T ₁' T ₂'ψ+ ( L/V ) ( T ₁'+ T ₂') ψ+ψ+ ( L/V ) ²α'ψ³= ( V/L ) K 'δ+ K ' T ₃'δ In the present report, a new method is proposed, to predict the various manoeuvring test results from the parameters of only one zig-zag test; the results of the spiral test, reverse spiral test, modefied zig-zag test, yaw-rate zig-zag test, course change test and so on can be obtained by numerical calculations. Next, we make also some considerations about the speed drop effect on the results of the zig-zag test, and propose a method to analyse the zig-zag test, taking account of it. Lastly, we make mention of the wind effect on manoeuvring tests.
